Pathogen inactivation of blood products represents a global and major paradigm shift in transfusion medicine. In the next near future, it is likely that most blood products will be inactivated by various physicochemical approaches. The concept of blood safety will be challenged as well as transfusion medicine practice, notably for donor selection or biological qualification. In this context, it seems mandatory to develop analytical economic approaches by assessing costs-benefits ratio of blood transfusion as well as to set up cohorts of patients based on hemovigilance networks allowing rigorous scientific analysis of the benefits and the risks of blood transfusion at short- and long-term. 相似文献

BACKGROUND: Elderly people often have multiple chronic diseases, are frequently treated by several physicians, and also use over-the-counter medications. Excessive prescribing, imperfect therapeutic adherence, treatment modifications after hospitalization, and oversized drug packages result in home storage of leftover drugs, resulting in a waste of healthcare resources. PATIENTS AND METHODS: All patients aged >/=75 years hospitalized for >24 hours during a 6-month period in an urban teaching hospital in Switzerland were eligible for inclusion in a study collecting sociodemographics, medical, functional, and psychosocial characteristics. Six months later, a research nurse visited the patients at home and recorded the names, number of tablets, and expiration dates of all open or intact drug packages, and the doses actually taken. Acquisition costs of these drugs were computed. RESULTS: One hundred ninety-five patients were included (127 women; mean age 82.2 +/- 4.8 y, range 75-96). They had a total of 2059 drugs (mean per patient 10.3 +/- 6.7, range per patient 1-42), corresponding to a total cost of (US) $62 826 (mean per patient 322 +/- 275, range per patient 10-1571). Self-reported drug intake was regular for 36% of the drugs (46.5% of total costs) and occasional for 11% (6.1%), whereas 35.7% (30.1%) had been stopped during the last month. Cardiovascular drugs amounted to 36.6% of the drugs and 55.5% of the costs. None of the patients' characteristics was significantly associated with a greater number of drugs and higher costs. CONCLUSIONS: Drugs stored at home by elderly patients were worth about $320 per patient. Only about one-third of these drugs were regularly taken. In the context of resources shortage, innovative solutions should be found to reduce the waste linked with drugs stopped in previous months. 相似文献

BACKGROUND: Quality indicators for dialysis care vary across countries and regions, but regional variability across centres has received little attention. We analysed variations in quality indicators among dialysis facilities in western Switzerland to identify opportunities for improving care for patients with end-stage kidney disease. METHODS: A cross-sectional study of 617 dialysis patients treated at 19 facilities examined the distribution of indicators of quality of care addressing: adequacy of dialysis (Kt/V > or =1.2 for haemodialysis, Kt/V > or =2 for peritoneal dialysis), anaemia control (haemoglobin > or =110 g/l), calcium and phosphate control (product < or =4.4 mmol2/l2), adequate nutrition (serum albumin >35 g/l), hypertension control (pre-dialysis blood pressure <140/90 mmHg) and type of vascular access. Centre quality targets were the following: achievement of quality criteria for 80% of their patients, except 85% for anaemia control and 60% for arterio-venous fistulae. RESULTS: Most centres fulfilled quality targets for dialysis adequacy, but substantial variations existed among centres (haemodialysis, 76%, range 36-100; peritoneal dialysis, 76%, range 33-100). Results were similar for anaemia (77%, range 35-100), calcium x phosphate product (69%, range 29-92), albumin (63%, range 26-95), hypertension control (33%, range 13-54) and arterio-venous fistula (61%, range 49-92). The between-centre variability was significantly greater than would be expected by chance, for all indicators. Dialysis facilities with >40 patients better fulfilled quality targets than university-based centres. Adjustment for patient characteristics did not modify these results. CONCLUSIONS: Substantial variations in quality indicators existed between dialysis centres in western Switzerland, which could not be attributed to different centre policies, or to differences in available measures of patient case mix. These findings indicate opportunities for improvement in dialysis practice which may translate into improved clinical outcomes. 相似文献

OBJECTIVES: To determine the incidence and identify risk factors of critical incidents in an ICU. DESIGN: Prospective observational study of consecutive patients admitted over 1 year to an ICU. Critical incidents were recorded using predefined criteria. Their causes and consequences were analysed. The causes were classified as technical failure, patient's underlying disease, or human errors (subclassified as planning, execution, or surveillance). The consequences were classified as lethal, leading to sequelae, prolonging the ICU stay, minor, or without consequences. The correlation between critical incidents and specific factors including patient's diagnosis and severity score, use of monitoring and therapeutic modalities was analysed by uni- and multivariate analysis. SETTING: An 11-bed multidisciplinary ICU in a non-university teaching hospital. PATIENTS: 1,024 consecutive patients admitted to the ICU. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The median length of ICU stay by the 1,024 patients was 1.9 days. Of the 777 critical incidents reported 2% were due to technical failure and 67 % to secondary to underlying disease. There were 241 human errors (31%) in 161 patients, evenly distributed among planning (n = 75), execution (n = 88), and surveillance (n = 78). One error was lethal, two led to sequelae, 26 % prolonged ICU stay, and 57 % were minor and 16 % without consequence. Errors with significant consequences were related mainly to planning. Human errors prolonged ICU stay by 425 patient-days, amounting to 15 % of ICU time. Readmitted patients had more frequent and more severe critical incidents than primarily admitted patients. CONCLUSIONS: Critical incidents add morbidity, workload, and financial burden. A substantial proportion of them are related to human factors with dire consequences. Efforts must focus on timely, appropriate care to avoid planning and execution mishaps at the beginning of the ICU stay; surveillance intensity must be maintained, specially after the fourth day. 相似文献

BACKGROUND: Adding temozolomide (TMZ) to standard radiotherapy as a first-line therapy for glioma may increase costs to a disproportionate degree compared with the resulting survival benefits. METHODS: Forty-six consecutive patients (28 males and 18 females; median age, 52 years; age range, 24-70 years) received concomitant TMZ with radiotherapy for 6 weeks followed by adjuvant TMZ for 6 cycles, and they were followed until disease recurrence and then until death. The authors assessed the costs associated with the four phases of treatment from a hospital-centered perspective. RESULTS: Treatment was discontinued early in 3 patients, 9 patients, and 15 patients during concomitant TMZ, before adjuvant TMZ, and during adjuvant TMZ, respectively. Karnofsky index values varied between 85% (at the beginning of treatment) and 76% (at the end of treatment). The nature of care after disease recurrence was diverse. Overall survival ranged from 1.4 months to 64.3 months (median, 15.8 months) and was better if surgical debulking could be carried out before treatment. Global costs amounted to Euros 39,092 +/- Euros 21,948 (concomitant TMZ, Euros 14,539 +/- Euros 4998; adjuvant TMZ, Euros 13,651 +/- Euros 4320; follow-up, Euros 6363 +/- Euros 6917; and recurrence, Euros 12,344 +/- Euros 18,327), with 53% of these costs being related to the acquisition of TMZ; this represented an eightfold increase in cost compared with radiotherapy alone. CONCLUSIONS: TMZ may be an effective but costly adjuvant outpatient therapy for patients with glioblastoma multiforme. Definite cost-effectiveness/utility must be assessed in a randomized Phase III trial. 相似文献

Acute rhinosinusitis is a common disease, in both children and adult patients, and happens most often in the setting of a viral infection with or without bacterial superinfection. Although spontaneous resolution is common, antibacterials are often prescribed and have a tremendous impact on costs, either directly or through the emergence of resistance in causative or colonising micro-organisms. The purpose of this work was to review published literature from 1989 to 2002 on antibacterial treatment in acute rhinosinusitis from a clinical and economical perspective. A relatively small number of studies have compared antibacterials with placebo and few have suggested that antibacterials are superior to placebo, except when a bacterial cause is established or in the presence of specific CT-scan findings. On the other hand, 58 randomised controlled trials were published between 1989 and 2002, that compared the relative efficacy of various antibacterials. Most of these studies had serious methodological flaws, and no single antibacterial proved superior to its comparators. Economic data are scarce and indicate cost of disease is high. Of the different treatment strategies assessed symptomatic treatment (patients being treated with antibacterials only if they failed to improve after 7 days) was the most cost-effective approach, compared with treating patients on the basis of specific clinical criteria, empirical treatment (all patients initially treated with antibacterials), or radiology-guided treatment. Cost effectiveness varied with disease prevalence. In conclusion, this pharmacoeconomic review of antibacterial use in acute rhinosinusitis shows the need for improvement in the quality of the studies feeding economic analyses, but suggests that huge financial interests are at stake. Savings achievable, by better targeting patients needing antibacterial treatment, could be substantial, and more practical and precise diagnostic procedures are clearly needed. Acute rhinosinusitis is a typical example of a clinical dilemma in which good clinical practice must be balanced against imperfect information and patients' individual interests balanced against society's interest. 相似文献

A new device for the analyses of nurses' satisfaction has been developed and validated on two types of general and intensive treatments at the University Hospital in Vaudois, Switzerland. A questionnaire has been elaborated for identifying the variables linked with characteristics of the nurse's work, as well as personal variables of the employer which could have an influence on the level of satisfaction. In identifying the sources of satisfaction and dissatisfaction, it has been possible to propose recommendations and corrective measures in order to improve the level of global satisfaction of the nursing team. 相似文献

Effectiveness and costs of care and treatment of recurrent malignant gliomas are largely unknown. In this study, 49 patients (32 males, 17 females; mean age, 49; age range, 23-79) were treated with temozolomide (TMZ) for recurrent or progressive malignant gliomas after standard radiation therapy. Cost assessment (payer's perspective) singled out treatment for first recurrence and all costs of care until death. We computed personnel costs as wages; drugs, imaging, and laboratory tests as prices; and hospitalizations as day rates. Patients were administered a median of five TMZ cycles at recurrence. Drug acquisition costs amounted to euro 2206 per cycle (76% of total costs). Seven patients showed no second recurrence (two are still alive), 16 received no further chemotherapy and died after 3.9 months, and 26 received second-line chemotherapy. After the second progression, median survival was 4.0 months (95% confidence interval, 1.8-6.1). Overall monthly costs of care varied between euro 2450 and euro 3242 among the different groups, and median cost-effectiveness and cost utility ranged from euro 28,817 to euro 38,450 and from euro 41,167 to euro 53,369 per life of year and per quality-adjusted life-year gained, respectively. We conclude that despite high TMZ drug acquisition costs, care of recurrent malignant gliomas is comparable to other accepted therapies. 相似文献
